To install Truck Lite driving lights on the R3 Touring i had to cut off the connectors that came with the lights (mine came with HD compatible connectors) and solder on like sized spade connectors that matched those on the bike's stock wiring harness.  I greased the connections with dielectric and  put everything back together.  Used them all year, so far no problems, have rode in some heavy rain. The LED driving lights put the stock lights to shame.
